Mai watsa bayanan sauti na bidiyo mara waya ta hanyoyi biyu da ake amfani da shi a ƙasa don 1-2 km
Mai watsa bayanan sauti na bidiyo mara waya ta hanyoyi biyu da ake amfani da shi a ƙasa don 1-2 km ya fi shahara, kuma muna samun sabon bincike. Kwanan nan, wani abokin ciniki ya so mu keɓance masa tsarin watsa bayanai mara waya ta hanyoyi biyu da sauti, wanda ake amfani da shi a wurin ginin. Halin yanayin amfani da ƙasa shine cewa duka mai watsawa da mai karɓa suna kan ƙasa. Kewayon watsawa da abokin ciniki ke buƙata shine 1-2 kilomita. Idan akwai cikas a tsakiya, Ana iya ƙara mai maimaitawa tsakanin mai watsawa ko mai karɓa don bayanan bidiyo da canja wurin sauti. A lokaci guda, idan aka samu matsala ta hanyar sadarwa mara waya, zaka iya canzawa zuwa watsa waya a kowane lokaci. Kuma akwai 4-6 kyamarori a wurin watsawa. Don haka ya zabi mai zuwa, Farashin 1752, bisa ga bayanan da ake bukata, TX900-2W-15KM ana ba da shawarar.
Mai watsa bayanan sauti na bidiyo mara waya ta hanyoyi biyu da ake amfani da shi a ƙasa don 1-2 kilomita.
Wadannan su ne takamaiman bukatun abokin ciniki. Zan amsa kuma in yi bayani daya bayan daya bisa takamaiman bukatunsa, me yasa wani salon ya fi dacewa ko shawarar.

9. RF Watsawa Ƙarfin buƙatun 5 wato PA (ikon amfilifa)
Samfurin Farashin 1752: Temporarily only supports 2W, 5W can not fit, has high power consumption, not have good heat dissipation.
Samfurin da aka ba da shawarar TX900 supports 2W, 5W, 10W.
10. Range tsawo:
I require a module to extend the range (Similar to a repeater station). It will increase the range by at least 500m and allow me to work in more complex NLOS situations. It takes the signal from the controller and relays it back to the vehicle and takes the signal from the vehicle and relays it back to the controller
The situation is a bit like this. It will help overcome extreme curvature. (Extender is not fixed to the ground! The image is symbolic)
If I place the repeater in between the controller and the vehicle, it will allow me to cross a more complex NLOS environment, and give me a greater range. (Ba na neman mai watsawa mai ƙarfi sosai don kawar da tashar mai maimaitawa.)

For ground use, it is hard to transmit 300km, as the earth is round, from the transmitter to the receiver, there are many obstacles.
You should consider doing 300km via a repeater (drone in the air)
Ina so in yi oda TX900, 802-826Mhz-2 watt, ya kamata in buƙaci allon daidaitawa don shi?
1. No configuration panel is required. The two-way wireless link directly accesses the node IP address of the wireless link through the network port web UI and has a built-in web server for parameter viewing and configuration.
2. Just like a wifi router, configure viewing parameters through the web UI.
